How to store checkbox array in a session, and then be able to add to it?

Posted on 16th Feb 2014 07:03 pm by admin

I'm trying to store an array of checkbox values into a session array, sort of like a shopping cart, but I can't figure out how to not overwrite the sessions array each time new checkbox values are added to the stored session...

Here is an array that is created upon submitting with two checkboxes checked:

Code: Array
(
[0] => 606613
[1] => 606614
)
And then my sessions array is now like so:

Code: Array
(
[checked] => Array
(
[0] => 606613
[1] => 606614
)

)
The code for that so far is this:

<?php
if (!isset($_SESSION['checked'])) {
$_SESSION['checked'] = array();
}
$_SESSION['checked'] = $_GET['new_checked'];
?>

I know I probably need to add a loop that checks the arrays, but I just can't think how I should go about adding newly checked checkbox values, that are not duplicates, to the *end* of the session array "checked"??

Would anybody care to share some ideas?
